Fuzzy logic temperature controller for small robots

Malfunctions in a working robot system are serious factors which can result in deviations from the desired goals. Among these, temperature increase over safe values is one of the most important factors that can limit the usage of available energy. The heat generated from motors and batteries can damage the electrical systems and affect the overall performance. This results in the need to control and maximize the utilization of supplied energy from batteries. In this paper, the authors designed an intelligent system to control temperature thus preventing system malfunction due to overheating in insulated robots, such as underwater robots. This temperature controller works in parallel with the robot motion controller. The proposed temperature control system uses fuzzy logic as a control layer system. It has been adopted to avoid system errors and efficiently use the energy available. The system is developed using fans, heaters and fuzzy logic circuits for achieving an energy efficient robot with long-term high performance.
